Dinosaur Tracks Museum—The best-kept secret in downtown Denver!!Did you know there is a dinosaur track museum on the University of Denver, Auraria campus?? It is located in the

basement of St. Cajetans Center at the corner of 9th St. and Lawrence Way. It is home to more than 2,000 specimens, including: –Colorado’s oldest known tracks –The world’s largest collection of pterosaur tracks –The first Tyrannosaurus rex and Triceratops tracks ever found –The world’s largest and smallest dinosaur tracks –The oldest hominid tracks in both the Old and New worlds...

Creator and director of the museum is Dr. Martin Lockley. His research has taken him to the Colorado Plateau region/western North America, South America (Bolivia), Europe (Portugal, Spain, U.K., Switzerland, Germany, France) east Asia (Japan, Korea, China) and Central Asia (Uzbeki-stan). “The collection, which is arguably the world’s largest and best documented, consists of more than 2,400 tracks (originals and replicas) of all ages from Carboniferous to Recent), a large number of which have been illustrated in several hundred scientific publications. The collection includes more than 75 type specimens of ceratopsian and champsosaur tracks (Ceratopsipes and Champsosaurichnus, from Golden, CO), Stegosaur tracks (Stegopodus, from eastern Utah), the first described Tyrannosaurus track (Tyrannosauripus from New

Mexico), the first large two-toed raptor tracks (Dromaeopdus from China), a large number of bird and pterosaur tracks new to science and the ancient human track Hominipes.”

Entrance is free, and the museum is open to the public during the spring and fall semesters. Special tours are available for groups and museum members. Call or email for current hours or to schedule a tour:

Museum office phone: 303-556-5261 Museum email: dinotracksmuseum@ucdenver.eduDirector’s office phone: 303-556-4884 Director’s email: martin.lockley@ucdenver.edu

Hurry before it’s too late! The museum will be moving to Boulder by 2012 where it will no longer be viewable by the public. Some of the collection will be moved this summer, so don’t dawdle! Get down there!

Parking is crazy when school is in session, so consider taking the light rail, or visiting on a Sunday when there are no classes and the parking is FREE. You can park right by the building.

GEORG PETERSEN (1898–1985): MINING AND METALLURGY IN ANCIENT PERU

by

William E. Brooks

Georg Petersen was born in Germany in 1898 and obtained his Ph.D. in geology from the National University of Kiel in 1922. He arrived in Perú in 1924 with a contract to manage the Zorritos oilfield, northern Perú. His ex-tensive bibliography, published in a newly mastered language, includes research on copper, gold, petroleum, salt, and tin occurrences, as well as reports on the archaeology, botany, climate, and history of Perú.

In 1952, he began teaching economic geology at the Universidad Nacional de Ingeniería. Then, in 1970, with encouragement from archaeologist and friend, Duccio Bonavia, Petersen published Minería y Metalurgia en el Antiguo Perú. Petersen’s book, essentially a De Re Metallica for the New World, includes 10 chapters, extensive endnotes, 13 black and white figures, many of which are photographs taken in the field by Petersen, and 22 tables that provide forward-thinking archaeometric data on ancient gold, copper, silver, and platinum artifacts as well as analytical data on smelter scoria and other geoarchaeological materials from Perú, Bolivia, Chile, Colombia, and Ecuador. His book blends archaeology, art history, biology, Colonial exploration, ethnohistory, geology, metal-lurgy, and the mining technology of the ancient Andes. Publication of Petersen’s book, in English, as Geological Society of America Special Paper 467, will help spread his academic and applied knowledge of the importance and use of mineral resources in the ancient Andes to a broad new audience.

(Note: abstract for second talk was not received by press time, but when received will be posted on the CSS website.—ed.)

Well, the February 16 meeting was certainly not one to have missed! I counted 109 people at our “Snowmastadon extravaganza.” Kirk Johnson and Jeff Pigati were captivating speakers, and the photos and descriptions of the numerous fauna and flora recovered were fantastic. I will be anxious to see what the summer field session recovers as the dig continues. If you missed the talk, the Denver Museum of Nature and Science has a great website to study. http://www.dmns.org/science/the-snowmastodon-project

The Thursday, March 24 meeting will be a historic tour of Peru, with a little something for everyone—geology, mining, engineering, hydrology, and archeology! William Brooks’ presentation on ancient mining in Peru, and Andrew Earles’ presentation on Machu Picchu should make for a fascinating evening. Let’s fill the auditorium at Berthoud Hall again!

I am glad to announce that our Emmons Speaker, Dr. Thomas Strasser, has rescheduled his talk on his new Archeologi-cal Discoveries on Crete for Thursday April 21. Due to room unavailability on campus, we will hold this talk at the new Golden High School auditorium. It’s only about a mile from the Green Center, and there’s plenty of parking! This may be an opportunity for us to develop a relationship with Golden High and interact with students there. Please contact me if you are interested in volunteering there to work with students and/or teachers.

This spring we have both William Brooks and Thomas Strasser joining us as speakers from out of town. We would like to plan an informal lunch and/or dinner for our guests while they are here, and invite interested members to host or join us for a visit and conversation. Please contact me if you would like to do so.

Cal Ruleman, our field trip chair, is working on our Spring Field Trip to Glenwood Canyon, tentatively set for May 6–7. Details will be announced as arrangements are finalized, .

I hope all have been enjoying the return of the refreshments at our talks. These are provided by volunteers, not from the CSS coffers. If you would like to donate food for a meeting or help cover these costs, please contact our Hospitality Commit-tee Chair, Ben Harrison. We are taking suggestions for goods/swag that display the CSS logo. What kinds of things should we order? Mugs, T-shirts, jackets, hats, pens… ???? What shall we give to speakers now that we are out of the current mug supply? Any ideas are welcome.

Please let me hear from you on these or any other topics!

Good Clean WWW Fun—(Thanks to Bruce Wahle for submitting these!)

Could Southeastern Utah Petroglyphs Represent Mammoths in the Ancient Southwest? While researchers in northern Colorado dig up the bones of giant Ice Age mammoths, others nearby in south-eastern Utah are looking at a very different record of these extinct creatures. High on a cliff overlooking the floodplain of the San Juan River, rock art specialists Ekkehart Malotki and Henry Wallace have examined several highly stylized images carved into the rock face including what they believe to be the first example of prehistoric Native American rock art to show a mammoth. While such images are common in the caves of Europe, they are surprisingly unknown in the New World. http://blogs.nationalgeographic.com/blogs/news/chiefeditor/2011/02/wildest-mammoth-in-the-west-fo.html

Indonesian mud volcano flow ‘to last 26 years’ The world’s largest mud volcano, which left 13,000 families homeless, is likely to continue erupting for anoth-er 26 years, researchers have estimated. It first erupted back in May 2006, and - at its peak - was spewing 180,000 cubic metres of mud a day, equivalent to 50 Olympic-sized swimming pools. The volcano, in East Java, Indone-sia, has buried homes, schools and farmlands over seven square kilometres. The findings have been published in the Journal of the Geological Society. http://www.bbc.co.uk/news/science-environment-12567163

Q U O T E D (from the MercuryNews.com)

“I turned the rock over and I saw the clavicle sticking out—that’s the collar bone. I didn’t know what it was at first; I thought it was just an antelope. So I called my dad over and about five meters away he started swearing, and I was like ‘What did I do wrong?’ and he’s like, ‘Nothing, nothing—you found a hominid’.”

—Matthew Berger, 9, son of South African professor and paleoanthropologist Lee Berger, describes the scene in 2008 when he found the first piece of what turned out to be the remains of two creatures who lived between 1.8 million and 2 million years ago and who may represent a new addition to the fam-ily tree of humans. The dig site, by the way, was chosen with the aid of Google Earth.

Can you believe it’s been 10 YEARS since the BBC program, “Walk-ing with Dinosaurs” hit the airwaves and became a sensation? A new show on BBC1 called “Planet Dinosaur” will further entrance us by using 3D graphics and computer-generated imagery. Fight scenes for the bloodthirsty viewers will of course be featured as well as new infor-mation about the “monsters.” Companion pieces on BBC4 will look at the story behind dinosaurs and prehistoric animals in “How to Build a Dinosaur,” and the issues of survival and extinction in “Survivors.” The season, which airs later this year, will be supported by website, learning, and interactive initiatives on BBC online.http://www.guardian.co.uk/media/2011/feb/28/bbc-show-3d-dinosaurs

For you Laramide Lovers...HOT off the PRESS!!!

Hydrodynamic mechanism for the Laramide orogenyby Craig H. Jones, G. Lang Farmer, Brad Sageman, and Shijie Zhong

Geosphere; February 2011; v. 7; no. 1; p. 183–201; doi: 10.1130/GES00575.1; 7 figures; 1 animation.

ABSTRACTThe widespread presumption that the Farallon plate subducted along the base of North American lithosphere

under most of the western United States and ~1,000 km inboard from the trench has dominated tectonic studies of this region, but a number of variations of this concept exist due to differences in interpretation of some aspects of this orogeny. We contend that five main characteristics are central to the Laramide orogeny and must be explained by any successful hypothesis: thick-skinned tectonism, shutdown and/or landward migration of arc magmatism, localized deep foreland subsidence, deformation landward of the relatively undeformed Colorado Plateau, and spatially limited syntectonic magmatism. We detail how the first two elements can be well explained by a broad flat slab, the others less so.

We introduce an alternative hypothesis composed of five particular processes: (1) a more limited segment of shallowly subducting slab is created by viscous coupling between the slab and the Archean continental keel of the Wyoming craton, leaving some asthenosphere above most of the slab; (2) dynamic pressures from this coupling localize subsidence at the edge of the Archean Wyoming craton; (3) foreland shortening occurs after the subsid-ence of the region decreases gravitational potential energy, increasing deviatoric stresses in lithosphere beneath the basin with no change to boundary stresses near the subduction zone or changes to basal shear stress; (4) shear between the slab and overriding continent induces a secondary convective system aligned parallel to relative plate motion, producing the Colorado Mineral Belt above upwelling aligned along the convection cell; (5) the develop-ment of this convective system interrupts the flow of fresh asthenosphere into the arc region farther west, cutting off magmatism even in segments of the arc not over the shallowly dipping slab.

USGS Updates Magnitude of Japan’s 2011 Tohoku Earthquake to 9.0Released: 3/14/2011 5:35:00 PM

The USGS has updated the magnitude of the March 11, 2011, Tohoku earthquake in northern Honshu, Japan, to 9.0 from the previous estimate of 8.9. Independently, Japanese seismologists have also up-dated their estimate of the earthquake’s magnitude to 9.0. This magnitude places the earthquake as the fourth largest in the world since 1900 and the largest in Japan since modern instrumental recordings began 130 years ago.

The USGS often updates an earthquake’s magnitude following the event. Updates occur as more data become available and more time-intensive analysis is performed. There are many methods of calculat-ing the energy release and magnitude of an earthquake. Some methods give approximate values within minutes of the earthquake, and others require more complete data sets and extensive analysis. Due to inherent uncertainties in the modeling of energy and magnitude, the results from different agencies often vary slightly. These magnitude discrepancies arise from the use of different data and techniques. For more information on why magnitudes change, see the Earthquake Hazards Program FAQ website. http://earthquake.usgs.gov/learn/faq/?faqID=297

SIGN UP for the USGS Earthquake Notification Service (ENS)!! It is a free service that sends you automated notification emails when earthquakes happen in your area. You can customize ENS to only deliver messages for certain areas, at speci-fied times, and to multiple addresses. ENS can even send text notifications to your cell phone.
